What is radio spectrum and why is it important to interoperability?
Radio spectrum is one of the nation’s most valuable, finite resources. It is electronic real estate—the complete range of frequencies and channels that can be used for radio communications. Spectrum is the highway over which voice, data, and image communications travel. Inadequate radio spectrum is a major barrier to effective emergency response communications, both in major events and in day-to-day operations. Without access to effective radio spectrum, emergency response personnel cannot communicate with their own agencies and with each other as needed.
